Hello,
Sorry to hear you are having trouble.
Ever since Windows 10 update KB4515384 (
link), Chrome window running in "app" mode no longer groups.
A previously saved group does appear as grouped when the system is restarted but is very buggy (ghosted windows, tabs do not switch between windows, etc.)
Currently running Groupy version 1.25.
Thanks!
Unless I am missing something you are doing, on both the general release of Win10, and the fastring, I am not seeing any grouping issues or tabbing with WinKey + ~ :

Saved groups with Chrome is always tricky as you need to ensure that all instances of Chrome are closed before you open a saved group with Chrome Windows Included:
